Understanding Lists, Tuples, and Data Conversion in Python A Step by Step Guide

Summary of Key Points:
Lists are mutable, meaning you can modify their elements.
Tuples are immutable, meaning once they are created, you can't change their contents.
You can convert between lists and tuples using list() and tuple().
Creating a single-element tuple requires a trailing comma, like ("item1",).
Tuples can contain elements of different types, and you can access their elements using indexing.
